Strong evidence · Two or more major antivirus engines agree.
Delete the archive without opening it; if the program inside was run, isolate the computer, run a full security scan and change your passwords from another device.
What to do now3 steps
This ZIP archive is harmful. Don't open or extract it, and delete it.
If you haven't opened or extracted it

If you already opened or extracted it
If you already extracted it, delete the extracted files too and run a full antivirus scan.
If a page it opened asked for a password or card details and you entered them, change that password and call your bank.

Why we think so
5 points against it and 0 in its favour, checked against the scan evidence.
The reasoning behind this verdict
This archive contains a single program disguised as a CAD viewer behind a document-style name. 31 of the 68 antivirus engines that checked it flag it, including eight major antivirus engines; DrWeb, Ikarus and Kaspersky label it a .NET remote-access backdoor (Quasar or AsyncRAT). It also references public IP-lookup services that such backdoors use to profile victims.
Detections are broad and heavy: 31 of the 68 antivirus engines that checked it, 22 of them independent, with eight major antivirus engines flagging the file. The named labels point to .NET remote-access backdoors, with DrWeb reporting QuasarNET and Kaspersky and Antiy reporting AsyncRAT. Our static analysis shows the archive holds one executable presented as a CAD viewer under a technical-drawings name, a common lure for business email attacks. The bundled references to public IP-lookup services fit how remote-access trojans fingerprint victims. The file is with a single submitter, and nothing in the evidence offsets these signals.
What We Detected
31 of the 68 antivirus engines that checked it flagged this ZIP archive, including eight major antivirus engines. DrWeb reports BackDoor.QuasarNET.3, Ikarus reports a Quasar trojan, and Kaspersky and Antiy report AsyncRAT; BitDefender and its licensees use a generic variant label. Our static analysis found three entries, one of which is an executable named as a CAD viewer, plus references to public IP-lookup services.
Threat Behavior
The document-themed archive name and fake viewer program are a typical delivery lure. No sandbox run is available, so this behaviour is inferred from the detections and static indicators rather than observed.
What To Do Now
Do not open the archive or run the program inside it. If the executable was already run, disconnect the PC from the network, run a full scan with up-to-date security software, and change passwords from a separate clean device.
Where this verdict could be wrong2 caveats
- family labels from major antivirus engines split between Quasar and AsyncRAT, so the exact family is not settled, though both are .NET remote-access backdoors.
- No sandbox run is available, so the backdoor behaviour is inferred from detections and static indicators rather than observed.
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.
- Eight major antivirus engines flag the file, 31 of 75 in total
- Several engines name remote-access backdoor families (Quasar, AsyncRAT)
- An executable disguised as a CAD viewer inside an archive named like technical drawings
- References to public IP-lookup services used to profile victims
- File seen from a single submitter

Threat context
How remote-access malware works
This opens a secret way into the computer. Once it runs, an attacker can control the PC from anywhere: see the screen, read files, install more malware or use the machine to attack others.
Bottom line:It is built to stay hidden and keep that connection open for as long as possible.

Programs inside
We opened the uploaded ZIP archive in an isolated sandbox and read its structure without running it. It contains programs. Our inspection reads the structure and the code of the first program; whether the programs are safe is judged by the antivirus and sandbox evidence.

An archive holds a single program next to documents or pictures, the way malware is often sent with decoy files. Software downloads also ship a program with a manual, so on its own this is only context.
